Σ workers×(1+wage_gap) + Σ WARN layoffs. The 1.0 base rate per certified H-1B worker request is a site model assumption. Wage gap multiplier = (BLS median − offered wage) / BLS median, applied only to filings offering less than the BLS median. Related research provides context, not validation of these exact coefficients. This is a modeled estimate, not a count of actual displacements.

Excess deaths over 20 years

Illustrative reference calculation · population applicability is not established

1,244.64

Range: 485.86 to 2,177.02

20-year reference scenario: high-seniority male displacement effect. This is not an expected count for an unknown population.

Source-profile mortality point (deaths)
1,244.63849002
No sustained excess from year 7 (deaths)
887.116911999

Declared structural comparison; not a confidence interval or a model probability.

Baseline population: US prime-age men (45-54).

Child lifetime earnings lost

Illustrative reference calculation · population applicability is not established

$29.8B

Range: $7.7B to $50.4B

Canadian father–son firm-closure effect, applied to a US male lifetime-earnings baseline in 2024 dollars. The reference result uses 2 children per worker.

Baseline population: US male median lifetime earnings.

The mortality effect comes from a high-seniority male study cohort. Treat the count as a reference scenario unless the population matches. A mixed population needs a reviewed transport rule.

The range is the engine's parameter-support envelope: it varies declared parameters only and adds none of the exposure input's uncertainty.

The math, limits, and citations

Illustrative reference calculations per 1,000 displaced workers and a standard family. Not a prediction about an individual or evidence that an entity caused displacement. Only county rows use county place inputs, including their WONDER-derived all-cause mortality baseline; all other types use the national reference.

Exact values: excess deaths over 20 years 1,244.63849002 (range 485.859762346 to 2,177.02104736); child lifetime earnings lost $29,760,044,109.35 (range $7,702,162,681.41 to $50,424,403,199.82);

Not included: exposure estimation error; baseline estimation error; unmodeled pathways.

Blocked model paths: local_service_jobs_lost: requires a documented net local loss of tradable jobs; worker displacement alone is not this exposure.
